Automation removed the shift-change handoff, not network control.
AI value · Driver-transfer road exposure
Company-reported
Road travel eliminated
Avoided exposure, not injuries prevented.
Before
Drives the heavy-haul train between mine and port until the 12-hour shift limit. → Travels to the train for mid-journey driver changes, requiring about 1.5 million road km annually.
After
Controls speed, braking, and responses to restrictions and alarms across the private mainline. → Monitor missions and manage stops, alarms, and network exceptions.
Human boundary
Automation drives routine missions; remote control owns network decisions.
Why it matters
Mainline driving can be automated while exceptions move to remote operations.
This case is company-reported. Use it for the operating-model shift; do not treat the numbers as independently measured.

Work that left the path
Mid-journey driver changes
1.5 million km annual relief-driver road travel
Human role before
Train drivers operated mine-to-port services until shift limits, while relief crews travelled by road for mid-journey handoffs under rail-safety controls.
Human role after
Remote operators monitor missions and manage exceptions.
AI role
Controls train speed, braking and alarm responses on the private network.
